Slovenian language added

[BlazOrazem]

I created new language files for Slovenian language, in which I translated english phrases. Afterwards I tested the CMS through and through with the Slovenian language, made some corrections and now everything looks great. I also translated Froala language file and system assets JS language file. Besides that I added Slovenian language to all other system language files and added a Slovenian language selection with an appropriate flag to the Preference model.

Thanks for your contributions @BlazOrazem! As this is a large PR with a lot to review we'll hold off merging it until after we've finished Build 460.

@BlazOrazem With the language changes made for Froala, would you mind submitting a PR to their repo to have the Slovenian language file added: https://github.com/froala/wysiwyg-editor. If we decide to update Froala, we will more than likely use their language files.
